# Touch LCD Shield Example
#
# Note: To run this example you will need a Touch LCD Shield for your OpenMV Cam.
#
# The touch LCD shield allows you to view your OpenMV Cam's frame buffer on the go.

# Initialize the lcd screen.
# Note: A DAC or a PWM backlight controller can be used to control the
# backlight intensity if supported:
# lcd = display.SPIDisplay(backlight=display.DACBacklight(channel=2))
# lcd.backlight(25) # 25% intensity
# Otherwise the default GPIO (on/off) controller is used.
# OpenMV Cam M4/M7/H7/H7 Plus -> DAC and GPIO Support
# OpenMV Cam RT1062 -> GPIO Support
# OpenMV Cam N6 -> PWM and GPIO Support
